Frequently Asked Questions
Is the Arctic Sport II Mid MAS12W21 waterproof?
Yes. It is 100% waterproof and 100% Muckproof — a molded rubber shell over a sealed neoprene bootie, so there are no seams to leak.
How cold can I wear the Arctic Sport II Mid?
Muck rates the comfort range from -40°F to 40°F. The 5mm neoprene bootie and fleece lining do the insulating; wear a wool sock for the coldest days.
How does the Arctic Sport II Mid fit?
It is built on a women's-specific last and comes in whole sizes — if you wear a half size, order up. The stretch-fit topline keeps snow out without cutting into the calf.
Does it have a safety toe?
It has a soft toe with no protective cap — a warm, lightweight winter boot rather than a rated work boot.
What is the bioDEWIX™ footbed?
A removable footbed treated with NZYM™ for odor control and moisture management; lift it out to dry the boot overnight.
How do I care for a Muck boot?
Rinse mud off with a hose, let the boot dry away from direct heat with the footbed removed, and store it upright out of the sun so the rubber stays supple.
